GEORGE C. FARKELL, OF ELYRA, OHIO.

MANIPULATOR.

Specification of Letters Patent.

Application filed February 24.-, 1915. Serial No. 10,253.

To all 107mm, it may concern Be it known that I, GEORGE C. FARKELL, a citizen of the United States, and resident of Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in llfanipulators, of which the following is a specification.

My invention relates to the art of rolling, and, while not restricted to such use, has particular reference to a novel manipulator used in handling rolled metal shapes.

An object in the design of the present device is to provide means for mechanically manipulating the shape or ingot in the interval between its travel through the various passes of a rolling mill. Heretofore, in many instances, this work has been performed by manual labor. As will be understood, this labor was extremely arduous, due

to the weight of the work and the attendant high temperature.

One of the particular objects in the construction of the present device is to provide for a motion approximating closely the motion attained by manually manipulating the Work, to the end that the work is not bodily lifted to any appreciable extent, thus economizing in the power required for the operation of the manipulator. A further advantage in thus minimizing the extent of movement of the work is in the economy of time required for the turning act. The results desired are accomplished in the present mechanism by very simple expedients. The mechanism will be more fully understood by reference to the accompanying drawings, wherein:

Figure l is a side elevation of a device constructed in accordance with my invention, Fig. 2 is a plan View thereof, Fig. 3 is an end view of the device, Fig. 4 is a front elevation of the construction shown in Fig. 7, Fig. 5 is a diagrammatic illustration of the location of the manipulator with relation to the roller feed table of the rolling mill, Fig. 6 is a diagrammatic illustration of the path followed by the work in being turned, Fig. 7 is' a side elevation of a 4slightly modified construction, and Fig.

Brackets 14 on the cylinder serve to support one end of tracks 15. The opposite ends of the tracks are supported on a hydraulic piston 16 coperating with a cylinder 17, which rests upon an abutment 18. Connected to the forward end of the piston rod 13 is a carriage 19 adapted for horizontal reciprocation upon the trackl. It will be seen by the arrangement described that the carriage is adapted for vertical and horizontal movement, due to the action of the fluid pressure means described.

Mounted upon the carriage 19 are sup* ports 20, between which a fluid pressure cylinder 21 is rotatably mounted. lVithin the cylinder is mounted a piston having a piston rod 22 the forward end of which en0'a fes a toothed segment 28 pivoted at 24 in a pair of frame members 25, which frame members are pivoted coincidently with the cylinder at the point 26. l/Vhile the frame member and piston are pivoted at the same point, they are adapted` for relative movement on their pivots. Engaging the toothed portion of the segment 23 is an idler 27, which, in turn, engages a toothed segment 28 car-V rying on one face thereof a wrench, or work manipulating memberl consisting of upper and lower arms 29, 30. The segment 28 is pivoted at 31 in the frame members 25. The idler 27 is mounted on a shaft, and secured to the shaft is a crank 32 which is connected to a link 33, the lower end of which vhas a fixed pivot 34 on the carriage 19.

lhe apparatus just described forming my improved v manipulator, is positioned between adjacent rollers of a feed table formed by the series of feed rollers 36 at a suitable distance from the reducing rolls of a rolling mill 35, as is shown in Fi'g. 5. The feed rollers 3G are shown in elevation relative to the manipulator in Figs. 1 and 7.

The operation of the device just described is as follows: While the work is leaving the rolls 35,-shown in Fig. 5, the manipulator, which is then located in a. position beneath the plane of the top of the feed table, formed by the feed rollers 3G, is raised by the fluid pressure piston 1G to the proper height. As the work leaves the reducing rolls of the rolling mill 35 the wrench is positioned properly by admitting fluid pressure tothe cylinder 12. Thereafter fluid pressure is admitted to the cylinder` 21 and the wrench is rotated on its axis 31 and coinciflentalh` lPatented Aug, 3i, i915.

is lowered bodily, by reason of the crank and link 82, 83, with the result that the center 87 of the work, as shown in Fig. 8, follows a line corresponding substantially to the full line 38 shown in that figure. lThe path of turning movement of the center 37 of the work (shown in Fig. 6 by the full line 88), closely approximates the path of turn-ing movement of the center 37 when the work is turned manually on the feed rollers 36 (a path corresponding to the line 39 of Fig. l5.) After moving the work to the position shown in dotted lines in Fig. 6, the carriage is actuated to move the wrench away from the work, whereupon the wrench is rotated to its originalposition and lowered out of the plane of the table.

ln' the consrtuction shown in Figs. 7 and 8 the elements correspond with those heretofore described, witli the exception that the wrench rotating cylinder `40 is pivoted to the carriage at 4l and is rigid with a frame 42. rilhe piston rod 43 terminates in a rack 44 having a guide slot 45 therein with which rollers 46 cooperate, such rollers being fixed on the frame 42.- The cam slot 47 is provided in the rack 44-with which slot a roller 48, mounted on standards 49 earried by the carriage 50 cooperates. Rigid with the frame 42 are standards 51, between which 'the toothed member 52 is pivoted at 53. inasmuch as the standards 5,1 have a vertical movement with relation to the standards 49 and roller 48, I have provided a slot 54 in the standards, which slot regis ters with the roller 48. The operation is substantially identical with that described in connection with the apparatus shown in Figs. 1 and 2, the movement of the work being the same in eachinstance. lt will be understood, of course, that on a return move` ment of the rack bar 44'the toothed member and the wrench are rotated and simultaneously lowered. This is an illustration of only one of the modifications which might be made in the apparatus described, and such modifications as arewithin the scope of my claims l mv invention.
